COUPLING ATTACHMENT.

Application filed January 26, 1918.

To all whom it may concern Be it known that I, DOMER A. BURNS, a citizen of the United States, residing at Miller, in the county of Cleburne and State of Arkansas, have invented certain new and useful Improvements in Coupling Attachments, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in coupling attachments and has relation more particularly to a device of this general character especially designed and adapted for use in connection with agrlcultural implements whereby such devices may be readily assembled in gang as the occasion of pract ce may require.

The inventionalso has for object to provide a novel andimproved coupling at tachment of this general character which is assembled in a manner to regulate or vary the space between coacting devices.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved coupling attachment whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure l is a view in top plan illustrating a coupling attachment constructed 1n accordance with an embodiment of my invention and in applied position;

Fig. 2 is an enlarged fragmentary view partly in elevation and partly in section illustrating certain features of my improved attachment Fig. 3 is a fragmentary view partly in elevation and partlv in section illustrating in detail one of the connections of my improved attachment with the frame of an implement; and

Fig. 4 is an enlarged sectional view taken substantially on the line t-i of Fig. 1.

' As disclosed in the accompanying drawin s the frames F for the rollers R are of su stantially the same construction as particularly set forth in my co-p nding appli- Specification of Letters Patent.

cation, Serial No. 208371, filed December 22,1917.

When it is desired, as on large plantations, to, employ the rollers R in gang, the frames are arranged in transverse alinement as indicated in Fig. 1 and said frames are maintained by my improved coupling attachment to be hereinafter particularly de scribed. Each of the frames F is adapted to have its separate draft team.

My improved coupling attachment comprises two substantially duplicate members and each of said members comprises parallel end members 1 of predetermined length and adapted to extend upwardly from the inner side portion of the frame F when in applied position. The lower portion of each of the end members 1 is provided with an eye 2 loosely engaged with an eye member 3 can ried by the intermediate portion of a substantially U-shape clamping member 4. The clamping member 4 straddles from above as herein embodied, an end beam of the frame F and has the free extremities of its arms threaded as at 5 and disposed through the extremities of the plate 6 underlying the end member of the frame F. Engaged with the threaded extremities 5 of the clamping member 4 are the holding nuts 7 contacting with the under face of the plates 6 and whereby the member 1 is effectively maintained in applied position upon the frame F The outer or opposite end portions of the members 1 are provided with the rectangular extensions 8 of desired lengths and the inner end portions of the members 8 are tied or connected by the interposed rigid member or strip 9 which serves to maintain the members 1 of a section in predetermined spaced relation. Men in applied position the extensions 8 extend laterally beyond the adjacent side of the frame F and are of a length to overlap the outer or free end portions of the extensions 8 of the second section as is clearly illustrated in Fig. 1. The free end portions of each pair of reversely directed extensions 8 are disposed through a block B and are capable of endwise movement therethrough. Each of the bores or passageways 10 in the block through which the extension 8 is directed, is intersected by an opening 11 in which is arranged a sleeve 12 through which an extension 8 is directed Threaded through the sleeve 12 is the binding screw 14 engageable with the extension 8. r g the medium f the s e e 1% arena and a Win aso b and the binding screws 14 it will be at once self-evident that the extensions 8 may be adjusted longitudinally through the blocks B so that adjacent frames F may be spaced apart at varying distance as necessitated by the requirements of practice as the binding members or screws 14 will hold 'the 'exten sions 8 against movement throl gh the sleeves 12 and as the sleeves 12 snugly lit Within the q ei ee 11, he bla ks E W 9 eff t v y hold the extensions 8' in the relative adlustnew:

It 'Will also be understood that my imm i memeteatime filed pos ss s a deoided advantage afforded bythe particule't' a iens v t t me e l are ea f vit t e ie F at w w e t ee re d y Pe m s an ndep n nt wleei e movement of the frames compensate for. the various inequalities in thesurface over whic tli i'elle' We te ti -elem nt tenei' s'e; rh' n assem led in gan fiwnme tn ee f nd se ured to, the
